When you talk about violence in the Qur'an, recall that the first ten years of it revelation, there are no examples of self defense. The early Muslims took a lot of punishment for their beliefs and each occasion, some ending in death, no order of self defense was practiced.
It wasn’t until Muhammad reached the city of Medina that Muslims were ALLOWED to defend themselves.
So any act of violence IS ALWAYS in the order of self defense. No where in the Quran are Muslims allowed to initiate force or violence.
Second, if we follow the logic of even “violent” versus, particularly where it suggest, “fight them until they submit” this versus is revealed in the context of Muslims having been persecuted by fellow Arabs for their religious beliefs. After negotiations, broken treaties and constant harassment that Muslims are thereafter order to fight them until they submit.
Is this not a reasonable order for war? Once war has arrived, is not complete domination the goal?
American police use excessive amounts of force to completely dominate the context to restore order. Is this not how order should be established in a context of tumult and oppression?
Again, if you don’t know the whole story, the human story, the good, the bad and the ugly, you will not understand why in certian places, pure might is obligatory.
